Active clinical trials for "Hypertension"

The purpose of this study is evaluate effects of TRAVATAN® versus LUMIGAN® on intraocular pressure (IOP) and ocular surface and inflammatory biomarkers.

The purpose of this study is the comparative evaluation of systolic blood pressure (SBP) lowering, atrial fibrillation (AF) recurrence and clinical data in patients with paroxysmal/persistent AF and resistant/non-resistant hypertension, undergoing AF ablation alone or combined with percutaneous renal denervation.

Blood pressure (BP) is believed to be a major determinant of vascular disease, and BP lowering is the most important goal in hypertension treatment. Thus, clinical guidelines for hypertension are mainly focused on lowering mean BP. However, despite an increasing incidence of stroke with age, the association between systolic BP (SBP) and the risk of stroke decreases with age. This disparity highlights a gap in the link between BP and vascular-related diseases (i.e., stroke). In clinical practice, visit-to-visit fluctuations in BP have been largely ignored and are thought to be an unreliable finding, even though this phenomenon is frequently observed. Rothwell et al. demonstrated that the visit-to-visit variability in SBP was a more powerful independent predictor of stroke than mean SBP, and that an increased residual variability in SBP in treated hypertensive patients was also a strong predictor of stroke and coronary events. Recently updated (2011) hypertension guidelines from the National Institute for Health and Clinical Excellence (NICE) recommend an angiotensin converting enzyme inhibitor (ACEi) [or angiotensin II receptor blocker (ARB)] and calcium-channel blocker (CCB) as a first line drug. Although the significance of BP variability (BPV) has been illustrated, the main focus of the current guidelines is to reduce systolic and diastolic BP, not BPV. In the X-CELLENT study, a CCB (amlodipine) and thiazide-like diuretic drug (indapamide sustained-release) led to a significant reduction in BPV, compared to an ARB (candesartan). In addition, the CCB showed the most effective reduction in systolic BPV among the antihypertensive drug class in a meta-analysis. However, there are no direct comparison studies of a CCB and ARB on BPV. Thus, we aim to compare the systolic BPV effects of a CCB versus an ARB in essential hypertensive patients. The primary hypothesis is that an ARB is not inferior to a CCB in the reduction of the systolic BPV standard deviation (SD) in essential hypertensive patients.

The study aimed to evaluate the chronic effects of resistance training on blood pressure and biochemical exams in hypertensive elderlies and the influence of the polymorphism of the angiotensin converting enzyme in these response.

The implementation of lifestyle modifications, home blood pressure (BP) measurement, and optimization of antihypertensive drug therapy have been shown to improve BP control in tightly controlled research settings. The investigators objective is to determine the effect of these interventions in a primary care setting, with the family practitioners and nurses serving as the interventionists. The investigaotrs hypothesis is that a comprehensive intervention performed in a primary care setting would lead to better blood pressure control.

The purpose of this study is to evaluate the intraocular pressure (IOP) lowering efficacy and the safety and tolerability profile of trabodenoson ophthalmic formulation compared to timolol maleate ophthalmic solution 0.5% in adults with ocular hypertension (OHT) or primary open-angle glaucoma (POAG) who are already receiving treatment with latanoprost ophthalmic solution 0.005% once every evening (QPM).

Isolated Systolic Hypertension (ISH)is the dominating hypertensive disease in elderly people. Much attention has recently been drawn to the strong relationship between the systolic blood pressure and cardiovascular morbidity. In previous clinical studies carried out in individuals with normal blood pressure at baseline SER100 decreased primarily the systolic blood pressure. It is hypothesized that the effect on systolic blood pressure in hypertensive patients will be larger or equal to the fall seen in normotensive patients.

This study will evaluate the safety, tolerability, and PK of MK-8892 in participants with pulmonary arterial hypertension. The primary hypothesis is that the geometric mean of MK-8892 area under the concentration time-curve from Hour 0 to 24 hours (AUC0-24hr) in participants with PAH, will be equal to or greater than the efficacious exposure in humans of 0.6 μM•hr.

This is a prospective, multi-center, non-randomized, feasibility study to assess the safety and effectiveness of renal artery sympathetic denervation using the investigational devices in subjects with resistant hypertension.

Multicenter, randomized, open-label, parallel-group exploratory study to explore the effects of azilsartan (Azirva), compared with telmisartan, on insulin resistance in participants with essential hypertension complicated by type 2 diabetes mellitus
